I honestly don't know how to rate this game.
The VN part? Definitely at least a 4, with a possibility of being a 5. It's genuinely great. From having read stuff on here, it appears as if the author misunderstands what makes the VN part so damn great. It's having a somewhat (at least in the beginning, I quit and uninstalled when Gloria was lvl 6, more on that later) decent story, good characters, and good character moments. The graphics and the lewd parts are also quite great. It could be better, but all of those things are very good.
What murders the game is the grind. Holy fuck the grind. I am convinced that the other reviewers are either paid shills or MMO players, nobody else would ever tolerate that grind. Spoilers ahead, but they're essential to understanding why I'm so upset with this.
Gloria lvl 6 follows yet another pretty grindy section, where the player has to waste time waiting for her desire meter to go up. But hell, at least there's something to like, do, while it's going up. The event happens and her Lewdness gets raised to 20. The next event requirement is to raise her Lewdness to 50.
The most efficient way of doing it that I found raises her lewdness by about 3 a week - it's waiting for her desire to go up, locking her, and spamming her with porn, then letting her cum when she gets to 6000 desire. That takes about 10 minutes of solid clicking. To get her Lewdness up by 3 points. You gotta do that 10 times. You can also explore other stuff, but at that point, there isn't much of that other stuff to explore. So you're stuck with an hour and a half of solid clicking. That's just unplayable. I might change this review if the author tells me a more efficient way to do this, that would get me through in like 20 minutes max, but as it stands - the game is unplayable.
That is honestly a real shame. While I'm not a big fan of NTR (and despite making fun of NTR, this game still has at least some with Gloria's elevator scene - we wanna get into her pants and she sleeps with someone else, that counts), the game is still real good. Like, really up there among the best games on here. But unless you're willing to edit save files all the time, which I'm not, you won't see any of it.
